150 This is one of the most universally diffused species in the Southern Hemisphere, and especially abundant throughout the Antarctic regions ; it bears considerable resemblance to the /. orbicularis, Mich., of North America, and to several other species. 18.

(Tab. LXIV. Kg. I.)

Hab. Campbell's Island ; in bogs on the bill-sides.

Caspites lati, interdum supra terram extensi, fiaccidi, sordide purpurei. Caules 1-J-- 2 unc. longi, erecti, superne incrassati, subdichotome ramosi. Folia valde concava et veutricosa, quasi inflata, amplexicaulia, rarius integra, segmentis aciuninatis, apicibus incurvis, substantia flaccida cellulosa laxe reticulata, vix pellucida. Stipules spepe latere unico solummodo dentatse, inajusculse, membranaceae, dense invbricatae.

The whole of the texture of this fine species is, when wet, so flaccid, that its large closely imbricated stipules are at first with difficulty distinguished from the leaves. It is perhaps more nearly allied to the /. serrulata, Sw. (Muse. Exot. t. 88), than to any other; still, this is quite a distinct plant, much larger, stouter, with the leaves somewhat fleshy and brittle, longer and more erect, of a lurid purple colour.

Hab. Lord Auckland's group and Campbell's Island ; creeping amongst mosses and other Hepaticce.

Gottsche (Synopsis, 1. c.) compares this species with J.piligera, Nees, a plant of Java ; it is perhaps more like ./. incumbens, Lehm. of Tristan d'Acunha, differing by the greater size and nearly equal segments of the leaves. These have no near ally in Europe. 20. Jungermanxia multicuspidata, Hook. fil. et Tayl.j laxe csespitosa, subramosa, prostrata, ramis interne radicantibus apicibus ascendentibus, foliis distantibus suberectis laxis obovatis bi-tri-quadrifidis segmentis acutis v. acuminatis laxe cellulosis, calyce terminali v. laterali elongato cylindraceo ore dentato.

Hab. Campbell's Island ; in pools, near the sea.

Caspites inter Sphagna repentes vel in aquam subnatantes, rarius supra terram in umbrosis, 1-2 unc. diametro, laxe intertexti, pallide albido-straminei. Caules subramosi, plerumque ad basin calycis innovationibus birds instructi, graciles, laxe fohosi. Folia pellucida, valde membranacea, ad medium divisa, sinubus obtusis, segmentis subdivaricatis ; pericluetiaUa erecta, laxe imbricata, plerumque tri-quadrilida. Calyx pericha;tio bis longior, elongatus, cylinchaceus, ore contracto insequaliter 3-5 dentato, latere fissus, infra orem obscure sidcatus.

This species has indeed many points in common with /. bicuspidata, the same pale colour, loose leaves with large cellules, acuminated segments, and an elongated calyx. It is marked by the smaller size, the stem-leaves being more erect, the division of the leaf deeper, and the calyx more generally terminal than in /. bicuspidata, L.
